如何在Python中循环CSV文件的一行?

Question

我有一个CSV文件，我想循环一列的值(在python中)。csv文件有5000行和两列。如何循环遍历第一列而不是第二列?

I tried doing

for row in df
for column in row

但这不起作用。我怎么修理它?

Answer 1

我会使用pandas来做到这一点…比如:

import pandas as pd
df = pd.read_csv('blah.csv')
column = df['column_name'] # column_name is the name of the column
for row in column:
print row

Answer 2

例如，您的df看起来像这样

column1    column2
0   name1   Address1
1   name2  Adsdrees2
2   name3   Address3

访问列1

for item, row in df.iterrows():
print(row['column1'])

#打印

name1
name2
name3
